NON-REFILLABLE BOTTLE.

Specification of Letters Patent. Application filed April 18, 1913.

Patented none 30, 1914. Serial No. 762,096.

To all "whomit may concern 7 Be it known that we, LOREN A. WI-IITING andGenre S. PARKER, citizens of the United States, residing at Hartford,inthe county of Hartford and State of Connecticut, have invented certainnew and useful Improvements in Non-Refillable Bottles, of which thefollowing is a specification.

Our invention relates toimprovements in non-refillable bottles, and'theobject of our improvement is to produce a bottle having a'neck providedwith a perforate plug of special formation" and an auxiliary corkwhereby the said bottle is made non-refillable and at the same time canbe manufactured by processes'that are ordinary and at moderate cost.

In the accompanying drawing :-Figure 1 is a side elevation of the neckand upper part of our non-refillable bottle. Fig. 2 is a plan view ofthe same. Fig. 3 is a sectional view on the line :0 w of Fig. 2, theouter cork being shown in broken lines. Fig. 4 is a side elevation, onan enlarged scale of the plug. Fig. 5 is a plan view of the same. Fig. 6is a bottom view of the same. Fig. 7 is a sideelevation of amodification of the plug. Fig. 8 is a plan view of the same. Fig. 9 is aside elevation of the auxiliary cork or stopper.

Our non-refillable bottle comprises a body portion 10 of usual form anda neck 11 of special form.

The neck 11 that comprises an is elongated and has a bore outer portion12 at the outer 'or upper end and an inner portion 18 that ispositioned. between the said outer portion 12 and the body portion-1O ofthe bottle. 7

The side wal of the'outer portion 12 of the bore deviates slightly fromthe cylindrical, havinga slight taper from the extreme outer end inwardthe entire length or up to the junction 1 1 ofthe same with the innerportion 13, and is of sufiicient length to house therein aplug 15 at thelower end and adjacent the said junction 14 and the outside or main cork16 at the outer end.

In some cases the main cork 16 may be seated on the plug 15.

The side wall of the lower portion 13 of the bore has a more appreciabletaper than that of the upper portion 12, being decidedly conical, sothat the extreme inner end 17 thereof is appreciably smaller in diameterthan the diameter at'the junction 14:.

The main cork 16 serves as the ordinary iii closure of the bottle and isof itself ordinary.

The plug 15 has an outer wall to fit the side wall of the upper portion12 of the bore and is provided with a plurality of ion gitudinalperforations in the form of channels in the periphery and of specialformation. The said perforations comprise three parts, respectively anupper passage 18, a middle passage 19 and a lower passage 20. The saidmiddle passage mon annular channel 19 which extends around the bodyportion of the plug 15 and at'about the middle portion thereof and whichforms a common connecting means for the several upper passages passages20.

The lower wall 29 of the channel 19 is plane and essentially annularbetween the 19 is part of a coin 131 18 and lower interruptions producedby the lower passages 20.

As shown there are three upper passages 18 spaced 120 degrees apart andthree lower passages 20, also spaced 120 degrees apart and the saidupper and lower passages 18 and 20 are positioned angularly theonebetween the other, or at an angular spacing around the axis of 60degrees between an upper passage 18 and a lower passage 20. Furthermore,the passages 18 and 20 are made relatively narrow circumferentially ivand long in the axial direction, all with a view to making the threepart passage composed of upper passage 18, intermediate or middlepassage 19 and the lower passage 20,

circuitous and to render it exceedingly dlificult and practicallyimpossible to force an implement or the end of a piece of wire admittedto any of the upper passages 18 through any of the lower passages 20 andinto the lower portion 13 of the bore.

The upper end 21 of the plug 15 is finished off plane and is suitablefor a seat for the main cork 16 and the lower end is provided at thecenter with a downwardly projecting lug 22, which as shown andpreferably is rounded. v

In the lower portion 13 of the bore there is housed an auxiliary cork orstopper 2a.

The said auxiliary cork 2 1 is of appreciable cordingly, when theauxiliary cork 2i is positioned in the upper end of the said lower part13, as when the cork is in contact with the lug 22, there is clearancearound the side wall 25 of the stopper 24 which permits of free passageof liquid. The amount of such clearance or play provided for the stopperis not sufficient to permit the stopper to turn end for end so that thestopper will always be properly directed to seat itself in the lower endof the lower portion 13 of the bore when there is no flow of liquidoutward and particularly, when there may be a flow of liquid in thereverse direction, as in case an attempt were made to re-fill thebottle.

The taper of the side wall 25 of the stopper 24,: and the side wall ofthe lower portion 13 of the bore is such that there will in no case be abinding engagement with one another, so that the auxiliary cork 24 willalways be free and unseated in case of the slightest tendency to flow ofliquid in the proper direction for pouring from the bottle. In the caseof the plug 15 however, because of the slight taper of the side wall ofthe same and the side wall of the upper portion 12 of the bore withwhich it is engaged there will be a firm seating of the plug 15 as a.result of even a slight pres sure on the outer end thereof. By havingthe main cork 16 seated thereon, such a firm engagement of the plug 15with the neck 11 is positively assured. Accordingly, the plug 15 afterbeing once firmly seated in the neck 11 is practically permanentlysecured therein, and cannot be removed without damage to the plugitself.

In the modification shown in Figs. 7 and 8 only two upper-passages 18and two lower passages 20 are shown, and these are somewhat larger thanthe passages 18 and 20. As described, the upper portion of the bore hasa slight taper; the lower portion has a taper somewhat more abrupt; thetwo taper portions merge at a slight angle and at a. plane substantiallytangential to the tip of the lug 22; the lower portion of the bore is ofsuitable length to permit of a movement of the auxiliary cork to providefor free outward flow of liquid; the relation of the length of theauxiliary cork and the taper thereof to th opposed walls of the lowertaper portion are such as to prevent a binding engagement, either by atoo firm a seating of the auxiliary cork at the inner position, as by atoo moderate a. taper, or by being tilted at; the outer position inrefilling, as with a too abrupt taper; the er p tion is of such lengthas to house the plug 15 and the main cork and without excess length; andthe length of the outer portion, the, length of the inner portion, andthe angularrelation of the tapered side walls of the said portions aresuch that a pocket or reservoir is avoided at the junction of the twotapered side walls, and thereby the collection of an appreciablequantity of liquid at the said junction is prevented, such as would tendto elevate the larg end of the auxiliary cork and to bind or cramp theauxiliary cork in the lower portion of the neck, particularly when therefilling operation is attempted with the bottle in an approximatelyhorizontal position.

In order to meet the requirements mentioned, particularly to preventre-filling when the neck is in an approximately horizontal position, wefind the arrangement and construction of details shown to beparticularly satisfactory and ell'ective,- and that a departuretherefrom to any appreciable extent will operate to prevent theachievement of the desired result. An especially important detail isthat of the angles of the tapered portions of the bore. These as shownare approximately one and one half degrees for the upper portion andnine degrees for the lower portion. Changing either of these angles asmentioned will render the device non-operative for the pur poseexplained above.

In the case of either style of plug the result of an attempt to pass awire through the plug would be to have the wire obstruct-ed by thebottom wall of the channel 19 and would o divert the end of the wire asto direct the same along the said channel and so as to avoid the lowerpassages 20 and 20.

lVhile our invention is shown as applied to a bottle, it is understoodthat the same is appliable to other structures, and whether made ofglass or porcelain such as demijohns and decanters, and kindred devices.

The device as described is also applicable for bottles havingconsiderable difierences in dimensions, by making proportional changesin the dimensions of the different parts.

While the features of the taper of the plug and the side wall areimportant in securing the plug in position in the neck, it is understoodthat in some cases some adhesive substance or cement may be used tocooperate in so holding the same in osition.

We claim as our invention A non-refillable bottle comprising a bottlebody and a neck at one end thereof, the said neck comprising an outerportion at the outer end and an inner portion intermediate the saidouter portion and the said bottle body and having a bore extendingthrough the said portions, the side walls of the part of the said borein the said outer portion having a taper of approximately one and onehalf degrees, the side walls of the part of the said bore in the saidinner portion having a taper of approximately nine do grees forming avalve seat, and a plug 15 position will force the cork to its seat bybeing fixedly positloned in the said outer the power of buoyancy.
